surron'r Forv TROLLEY oolvnuoron-sh Application filed June 3,

To all whom it may concern.

Be it known that I, HOMER P. CHANDLER, a citizen of the United States of America, residing at Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements ina Support for Trolley Conductors, ofwhich the following is a specification.

y invention relates to a support for trolley conductors and more particularly to that class of supports known as a trolley clamp or ear. a

The object of my invention is to produce an ear or clamp which does not require the use of screws, bolts, screw drivers or other tools or fastening devices, as such, to secure the clamp or ear to the trolley wire. I speak of my invention as being a trolley. clamp or trolley ear for the reason that it partakes of the nature of bot Y My invention resides more particularly in the jaw members or lips which directly grip the trolley wire and is due to the resilient character of the lips or jaws, which in turn is due to the property of the material entering into the construction of the lips or aws.

J In the drawing accompanying this specification:

Figure l is a side view in elevation of my invention shown as positioned on a trolley wire.

Fig. 2 is an end view in partial section.

Fig. 3 is an enlarged view of a portion of the jaws or lips which grip the trolley wire and points out particularly the serrated or tooth character of the gripping edges of the jaws or lips.

In my preferred construction I employ a body member 1 provided with a boss 2 which is'internally threaded in order to secure the supporting device to an overhead support, such as an insulated hanger, etc, commonly used for this purpose. The body member .is

' also provided with an elongated section 3 which in turn has a longitudinal groove 4 adapted to receive the .jaw members The jaw members are secured in position in the groove at by means of rivets or other fastening devices 6. These fastening devices 6 may be removable or permanently fixed in 1922,. Serial no. 565,615.

place, and, as I haveshown them, they com prise rivets permanently secured in position; he jaw members 55 are made preferably of a rather thin sheet metal formed to the necessary shape, preferably ball, rolled phosphor bronze which has high resilientvqualities, or of steel also having high resilient qualities. The latter material may be either tempered or untempered depending upon the amount of resiliency, stiffness, etc., required which in turn may be ,efi'ec'ted by the shape and size of the jaw members 55. I prefer to make the slot at of such widthas to receive the molded portion 7 of and this material is the jaw members with j a snug; fit so that there will be no yielding gagement thereby causing both jawnaembers to spread apart and then spring into the groove of the trolley wire after the supporting device and trolley wire have been brought into proper position, or one jaw, may be entered in one groove of the trolley wire and then either the trolley wire or the supporting device twisted about the engaging point of the jaw with the trolley wire thereby causing the jaws to spread sufficiently for the entranceof the trolley wire. a

In order to eliminate relative lateral movement of my invention with respect to the trolley wire, I serrate the portion 88 of the jaws 5 thereby forming small teeth or serrations 9 upon the engaging portion of the jaws which I find will eliminate relative lateral movement of the support and trolley wire. These serrations or teeth 9 may formed as by means of a stamping die or by means of a chisel cut. the latter producing a slightly raised tooth, while the former will produce a toothor serration as shown.

I find that With the use of proper matethe trolley wire is securely it is possible by applying sufiicient force to the trolley wire to remove it from the ear thereby being able to again utilize the ear to support another wire.

It is quite possible that supporting devices having lips or jaws possessing a resiliency to a degree have been used in the past as nearly all materials which would ordinarily be used in a device of this character, possess some resiliency, but I am not aware that any attempt has been made to utilize the resilient property of the metal exclusively where gripping the trolley wire.

My invention produces a cheap, efiicient device and at the same time one which is quickly applied to or removed from the trolley conductor and either of these operations may be efi'ected without the use of tools.

There are no doubt modifications which my disclosure will suggest to those skilled in the art and which will fall within the scope of my invention, and therefore I desire not to be limited otherwise than by my claims.

I claim:

'1. A conductor support comprising a body member provided with means for attachment to a support, a pair of resilient clamping jaws secured within the support and having parts projecting without to grip a conductor, said grip being entirely due to the resilient properties of the projecting part of the jaws.

2. The combination with a body member and means thereon to secure the body mem ber to a support and having means to receive a pair of resilient clamping jaws to grip aconductor of a pair of clamping jaws securely held within said means and having a portion projecting therefrom, said projecting portion arranged to spread apart under pressure to permit the positioning of the conductor therebetween and spring together due to the resiliency of the jaws to engage and grip the conductor.

3. The combination with a body member and means thereon to secure the body member to a support, a pair of conductor engaging jaws formed up out of a resilient sheet material to grip a conductor and having a portion rigidly heldin engagement with the body member and having a portion projecting therefrom and free to be forced apart against tension of the jaws to receive a conductor and free to spring into engagement with the conductor due to the tension of the jaws when the spreading face is removed.

4:. A supporting device for a conductor comprising a body member having means for attachment to a support and resilient conductor engaging jaws secured to the body member and normally held a fined distance apart and tree to spring back to their normal position due to their resilient character when a force spreading them apart is removed.

5. A supporting device for a conductor comprising a body member, means to secure the body member to a support, and resilient jaws secured to the body member to engage and grip a conductor due to the resilient character of the jaws.

6. A supporting device for a conductor comprising in combination a body member means to secure port a pair of resilient conductor engaging jaws to grip a conductor, said resiliency forming a component part of the jaws to move them into engagement with the conductor and maintain them in engagement.

7. A supporting device for a conductor comprising in combination a pair of uni tary cooperating members each having a portion held in rigid engagement with each other and a resilient portion separated from the other and free to move relative to each other to engage and grip a conductor.

8. A supporting device for a conductor comprising in combination a pair of jaws having resilient means to move the jaws toward each other to grip a conductor, said resilient means comprising a component part of the jaws.

9. A supporting device for a conductor comprising in combination a pair of holding members having means to secure the jaws to a support and means to engage with and grip a conductor and means on the engaging edge of the jaws to prevent longitudinal movement of the conductor relative to the jaws.

10. A conductor supporting device com prising a pair of resilient holdingmembers to engage and grip a conductor and means on the engaging portion of the holding members to prevent relative longitudinal movement of the holding members and the conductor.

11. A conductor supporting device comprising a pair of resilient holding members to engage and grip a conductor and a plurality of serrated-like-means on the engaging portion of the holding members to prevent relative longitudinal movement of the holding members and the conductor. I

12. A supporting device for a conductor comprising in combination a pair of jaws having resilient means to move the jaws toward each other to grip a conductor, said resilient means comprising a component part of the jaws and means on the gripping edges of the jaws to prevent relative lateral movement of the jaws and conductor.

13. A supporting device for a conductor comprising in combination a body member, means to attach the body member to a support and a pair of holding members possessthe body member to a supfrom and means to secure the j aws therein, the projecting portion of the jaws possess- 10 ing resiliency to return them to a predetermined distance apart after being forced a greater distance apart. r

In testimony whereof I aflix my signature.
